How to transform a content into a shiny Playlist?

I was thinking about rewrite the whole architecture of the project.
## Problem

Basically, the project follow this logic:


Where `content` is a string to parse (plain text, xml, etc.), `type` is an enum of supported type (xpsf, m3u, etc), and `object` is the playlist created by PlaylistSharp.

Our work is to create the magic to achieve this: "How to transform a content into a shiny Playlist?"
## Solution

For know, the project is following an OOP-ish architecture. Should we:
- Keep the project like this and update it.
- Rewrite the project from scratch with a new OOP architecture.
- Move to a more functional architecture.

Any thoughts?
